Intel 82579V NIC problem - kernel regression?

andrew-wja · 2012-01-09 21:16:34

Hi all,

I recently upgraded my desktop motherboard to an Asus Maximus GENE-IV, which has the Intel 82579V Gigabit NIC. I installed arch the usual way, dd-ing the latest install image onto a USB stick, and what have you. Trouble is, as soon as I upgrade the kernel and reboot, my NIC stops working in a peculiar manner. It will come up after I do 'sudo ip link set eth0 up', and acquire a carrier. Then, after about ten seconds, the carrier drops. Then it'll come back up again... and drop again. Over, and over, and over. This does not happen with kernel 3.0.3, which is the kernel installed by the latest install image, but it happens with every kernel from 3.0.7 onward (3.0.7 is the oldest kernel I have available to test with, from /var/cache/pacman/pkg on another machine). The most frustrating thing is that I've been googling the problem for two days now, and I can't find anyone who has quite the same issue

The driver is e1000e, and it's autoloaded. My system is an x86_64 one. Has anyone experienced this themselves or heard of it anywhere else? I'd like to avoid manually building the intel driver sources if it's at all possible, because it works fine with an old kernel. /frustration

Edit: dmesg is flooded with "e1000e: eth0 NIC Link is Up" messages.

Edit: further weirdness: when I set a static IP on boot from rc.conf, the interface stays up, but I can only see machines on my local network - DNS does not work, even after putting a nameserver entry into resolv.conf and rebooting.

Edit: I did a clean install, marked the linux kernel as a package not to be upgraded, and did a pacman -Syu. Even with the old 3.0.3 kernel, after the update, my NIC is broken in exactly the same way. I'm really stumped on this!

Works fine here, same driver, static IP though.

Ah, I see you're on i686. I should have mentioned this in the top post, and I'll edit it now, but I'm on x86_64. I tried setting a static IP, but as soon as the carrier drops, it's gone... it rarely stays up long enough to dhcp, but it does sometimes. I ran 'while true; do ip addr | grep eth0; sleep 1s; done' and you can see it come up and go down every ten-ish seconds. I've no idea what's going on...

Hmmmm... I notice your dmesg output says link is up, flow control: rx/tx, whereas mine says flow control: none
